DC-ROADS: ROADS as a (Dublin Core) Metadata Management Environment
The need for structured metadata to describe resources on the web is
widely acknowledged. The Dublin Core  provides a
standard element set to support resource discovery. Dublin Core
metadata can be embedded in web pages using HTML meta tags or using an
XML encoding of RDF.
The underlying technology is available to support the embedding of
Dublin Core into web pages; the next step is to provide a web site
development environment that supports the creation and management of
such metadata in an integrated manner.
- The metadata author should not need to understand any particular
syntax for encoding Dublin Core. Only an understanding of the Dublin
Core element set should be required.
- The process of metadata creation and editing should be
straightforward and a natural extension to web site development.
- It should be possible to view the metadata in a human-friendly
format with the option to offer this view as a part of the web site.
- Metadata should be accessible via open standards to support the
use/development of additional tools - e.g. a site wide search engine.
This document describes an integrated environment for associating
Dublin Core metadata with the resources on a website. This work
develops and extends an approach suggested by Andy Powell . The solution is
based the ROADS resource discovery toolkit 
The result is a system that allows users to enter (or update) metadata
for the local resource currently being viewed by clicking a `personal
toolbar button' on the browser - this takes the user to the ROADS
editor where metadata can be entered using a Dublin Core ROADS
template. The metadata is then stored in a ROADS database. By
embedding a server side script into HTML resources the metadata for a
page can be automatically extracted from the database and inserted
into the web page as an HTML meta-tag or RDF/XML representation of
Additional features of the system are the ability to easily add a
search facility to a website using the ROADS toolkit and the simple
provision of a viewable form of the metadata also generated
(Note that the `Edit DC' button only appears in the browser of the web
editor, not the end user and that access to the editor is password protected.)
The Dublin Core metadata on the eLib website 
is managed using the approach described here.
The details of this system are described in separate documents:
Additionally, there has recently been discussion of the need for a DC-in-a-Box solution for Dublin Core metadata management and deployment. The following document discusses the potential of DC-ROADS as a DC-in-a-Box:
